Precipitator Line Offers "Green" Air Cleaning Technology

Operating on 0.7 amps per 1,000 cfm ofcapacity, Smog-Hog electrostaticprecipitators captures up to 99.9 percent of submicron smokes, mists andemulsion oils using washable collection cells. Green advantages for the systeminclude reusable collection cells, minimal fan size, low energy use, make-upair reduction, potential material recycling and elimination of costs for filtermedia disposal and replacement. Smog-Hog mist collectors are available forindoor or outdoor use, for small source-capture applications down to 200 cfm,or large process exhaust streams up to 40,000 cfm. The Smog-Hog is useful formeeting OSHA and EPA regulations regarding metalworking oil smoke and coolantmists, welding smoke, quenching smoke, plasticizers, cooking smoke, asphaltsmoke and similar mists.

Smog-Hogs use electrostatic precipitation (ESP)to capture particles down to 0.01 microns in size. Depending on systemconfiguration, various prefilters and/or mist-stop filters capture the largestparticles first. Smaller particles are electronically charged in an ionizingsection and then captured on closely spaced plates in a collecting cell, muchthe way lint is attracted to a wool suit by static electricity. Cleaned air canbe recirculated into the plant, reducing make-up air requirements up to 80percent to save energy, or the air can be released to atmosphere. Capturedliquids drain from the collection cell for convenient disposal, reuse orrecycling.

Unlikefiltering devices, static pressure of the Smog-Hog is extremely low - about 0.25 inches W.G. - requiring about1 hp of fan energy per 1,000 cfm of system capacity. Thus, noise, total energyuse and operating cost are low and fan silencers are eliminated.

Smog-Hogsystems can be used ducted or unducted, and smaller models can be mounteddirectly on machine-tool enclosures. The smallest model, the MSH, includes a variable speedcontrol to minimize energy use and control air flow from 200-600 cfm. MSH unitshave a total energy input requirement of 1.4A, and their large-capacity ESPcells capture up to four times the amount of machine fluid of similar sizeddevices. Larger SHN and SG models handle air volumes of 400-9,000 cfm. SHN andSG models can be machine mounted, but these units are more commonly ducted tomachine enclosures or used unducted to clean and circulate air in specificzones of a plant. Many Smog-Hog units come with a high-efficiency mist-stopfilter or can be equipped with it as an option. The mist-stop filterdramatically reduces the amount of mist and smoke passing through theprecipitator's collecting cell, allowing the units to operate two to threetimes longer without maintenance.

Custom-engineeredPSH and PSG models of the Smog-Hog are designed tocollect heat-generated organic vapors and particulates from industrialprocesses, and use a variety of filtering technologies to precondition andclean the most polluted airstreams. Typical applications involve visibleindustrial emissions from asphalt coating, CNC machinery, industrial cooking,plastics, textile and rubber processing, as well as soldering, sintering, lasercutting and etching. These modular systems handle airflows of 750-40,000 cfm.The precipitator modules use a low-energy, self-regulating power supply thatadjusts voltage based on contaminant loading, for safe and continuous operationat the highest efficiency level. Smog-Hog ionizers and collecting cells utilizea unique airfoil design with convoluted insulators and heavy-duty tungstenionizer wires.
